Question

Forece increases in surface tension what happens area

Answer 1

Surface tension is the attractive force in liquids that pulls surface molecules into the rest of the liquid, minimizing the surface area. These attractive forces are due to electrostatic forces. We typically refer to this cohesion at the gas-liquid surface (not liquid-solid or liquid-liquid surfaces). We often see this occur with water, but it occurs with all other liquids to some degree.

Also Surface Tension can also be defined as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of inter-molecular attractive forces, the cohesive forcesbetween molecules.

It has the dimension of force per unit length, or of energy per unit area. The two are equivalent, but when referring to energy per unit of area, it is common to use the term surface energy, which is a more general term in the sense that it applies also to solids.
